	Sirius - Crystalinks
		Sirius is the brightest star in the night-time sky with a visual apparent magnitude of -1.47.
		Sirius is roughly half the age of the other members of the stream, so their common motion is most likely a coincidence.
		Sirius was worshipped as Sothis in the valley of the Nile.

	Sirius - MSN Encarta
		The star was highly venerated by the ancient Egyptians, who regarded it as a token of the rising of the Nile and of a subsequent good harvest.
		The brilliance of Sirius is in large part a consequence of its relative nearness to the earth.
		Irregularities in the motion of Sirius led the German astronomer Friedrich Bessel to believe that the star was accompanied by a hitherto unseen companion star.

	Sirius - Wikipedia, the free encyclopedia
		In 2005, using the Hubble Space Telescope, astronomers determined Sirius B to be 12,000km (7,500 miles) in diameter, with a mass that is 98% of the Sun.
		Sirius was worshipped as Sothis in the valley of the Nile long before Rome was founded, and many ancient Egyptian temples were oriented so that light from the star could penetrate to their inner altars.
		Sirius was commonly thought to cause madness in 18th century England, and is alluded to in John Dryden's religious and political satire "Absalom and Achitophel," in the context of showing that it would plainly be mad to think that Charles II should "displease" the English people (LL.333-334).

	Sirius
		Sirius is a white A1Vm main sequence star having 22 times the luminosity of the sun and 1.6 times the sun's diameter.
		Sirius B reveals with a 50 year period in an orbit with a separation of about 20 AU between the two stars.
		Sirius B must be a star having almost the mass of the sun packed into a volume smaller than that of the earth.

	Sirius Satellite Radio - Wikipedia, the free encyclopedia
		Sirius Satellite Radio NASDAQ: SIRI is a satellite radio (DARS) service based in New York City that provides 68 streams (channels) of music and 55 streams of sports, news and entertainment to the United States and Canada.
		Sirius currently has fewer subscribers compared to competitor XM Satellite Radio, with 4 million, less than XM's current audience of roughly 6.5 million (as of April 13, 2006).
		The dog in the Sirius logo (Sirius is referred to as the "Dog Star") is unofficially named “Mongo,” a name garnered from the debut of Sirius Satellite Radio’s sponsorship on Casey Atwood’s and later Jimmy Spencer’s NASCAR entry, when the announcing cast voted on names.

	Sirius (Alpha Canis Majoris)
		The primary (Sirius A) is a white A star.
		The companion (Sirius B, or "the Pup"), orbits with a period of 49.97 years, and was the first white dwarf to be discovered.
		Following Bessel's suggestion (1844) that Sirius had a dark companion to account for the star's wobbling movement, this object was optically identified by Alvan G. Clark in 1862.

	Sirius
		Sirius is the luminary of the constellation Canis Major, the Greater Dog, which represents Orion's larger hunting dog, and as such is commonly referred to as the "Dog Star." So great is its prominence that it has two "announcer stars" that from the mid- northern hemisphere rise before it, Procyon and Mirzam.
		Because of its brilliance, Sirius is the champion of all twinklers, the effect caused by variable refraction in the Earth's atmosphere.
		Sirius is "metal rich," its iron content triple that of the Sun, most likely from some sort of elemental diffusion.

	Sirius 2
		Sirius is composed of a main-sequence star and a white dwarf stellar remnant.
		However, Sirius B was not actually observed until January 31, 1862 by Alvan Graham Clark (1832-1897), who was testing a new 18-inch telescope built for Dearborn Observatory by the famous company founded by his father (Alvan Clark) and later run by his brother and himself.
		Sirius B was the first White Dwarf to be discovered, but it took almost a century from its discovery to the wide acceptance of its nature as a stellar remnant.

	Science Line - Night Patrol - Constellations - Canis Major - Sirius (Site not responding. Last check: )
		Sirius is a remarkable star, it is not one of the Galaxy's most luminous stars but appears so bright owing to its relatively close distance of 8.7 light-years (on the order of 80 million million km) - hence one of the Sun's neighbours.
		Sirius is accompanied by a much fainter smaller star known as Sirius B - or the 'Pup'.
		Too faint to be seen without moderate sized telescopes, Sirius B is a prime example of a 'white dwarf' star - a tiny, incredibly dense object (a tablespoon full of this matter would weigh 2.5 tonnes!) approximately 32,000 km in diameter.

	Sirius
		Sirius is visible on the far left of the above photograph, to the left of the constellation of Orion and Comet Hale-Bopp.
		In 1862, Sirius was discovered to be a binary star system with a (twin) companion star, Sirius B, 10,000 times dimmer than the bright primary, Sirius A. Sirius B was the first white dwarf star discovered, a type of star first understood by Subrahmanyan Chandrasekhar in 1930.
		The companion, Sirius B, is a white-dwarf star and has also been the object of considerable study because it is the first white dwarf whose spectrum was found to exhibit a gravitational red shift as predicted by the general theory of relativity.

		According to their traditions, the star Sirius has a companion star which is invisible to the human eye.
		Sirius A is the brightest star in our sky and can easily be seen in the winter months in the northern hemisphere.
		In the 1920's it was determined that Sirius B, the companion of Sirius, was a "white dwarf" star.

	Sirius
		Sirius has a long, exalted history and plays a prominent role in our planet's greatest empires, the most outstanding of which was ancient Egypt.
		Sirius represented, therefore, the religious concept of renewal as an extrapolation of the annual flooding.
		More prosaically, Sirius is also the key to survival, the organization and use of time, and the successful management of civilization.

		Police K9 Sirius was a bomb detection dog with the Port Authority of New York and New Jersey Police Department.
		Lim commented to Sirius, "...one must have gotten by us." Of course, that was not the case because the explosion Lim heard was caused not by a surreptitiously placed bomb, but by one of the hijacked planes crashing into the building.
		Thus on September 11th, Sirius, a well-trained bomb detection dog, whose life was dedicated to the dangerous job of searching for bombs as part of America's "War on Terrorism," died ironically in a terrorist attack that even he, with all his training and experience, was powerless to detect.

	Sirius Mystery, Dogon tribe (Skeptical Inquirer Fall 1978)
		Probably Sirius B spilled over some of its gas onto Sirius A during its aging process, so that the original masses of the two stars were approximately the reverse of what we see today.
		Sirius B is now emitting soft x-rays, so that life in the region of Sirius would not be very pleasant today.
		Sirius B was certainly the smallest and heaviest star known in the 1920s, when the super-dense nature of white dwarfs was becoming understood; the material of which white dwarfs are made is indeed compressed more densely than metal.

	The Star Sirius
		Sirius B is a "white dwarf" star, invisible to the naked eye and packing the equivalent mass of our sun into an incredibly dense globe only 4 times the diameter of our Earth.
		Sirius B traces an elliptical orbit around Sirius A, and their common center of gravity, directly face onto the Earth like the dial of a clock.
		As Sirius B moves past periastron, the light generated by their shared energies begins to diminish until eventually, it resumes its role as her "Dark Companion".

	The Mysteries of Sirius
		They go on to say that the start's orbit is elliptical, with Sirius A at one focus of the ellipse, that the orbital period is 50 years (the actual figure is 50.04 plus or minus.09 years), and that the star rotates on its own axis.
		In 1915 the first spectrum of Sirius B was obtained by W.Adams at Mt.Wilson, which is all that would have been needed to classify it as a white dwarf.
		Sirius, the dog star, stands for the spirit of wisdom in the Zoroastrian tradition.
